Description

Technical Field

[0001] This utility model relates to the field of underwater mud pumping construction technology, and in particular to a mud pumping device. Background Technology

[0002] Most bridges spanning rivers require foundations in the riverbed, with drilled pile foundations being the most common. Before drilling, casings are installed. After the concrete is poured, the casings accumulate significant amounts of silt due to drilling or summer flooding, which is difficult to clean once settled. Following pile construction, pile caps need to be built within cofferdams, where silt also accumulates, and the settled mud is difficult to remove. Common silt removal methods include manual cleaning or using mud pumps with divers to disperse the silt with high-pressure water jets before pumping it out. Both methods are slow and pose a high risk to personnel.

[0003] Therefore, how to clean up the mud is a key technical issue that needs to be considered during construction, as it not only affects the quality and efficiency of construction, but also construction safety. Utility Model Content
